Parthenolide from the aerial parts of Tanacetum larvatum
(Oxford : Pergamon-Elsevier Science Ltd, 2001)
The genus Tanacetum L. comprises ca 150 species that commonly occur in Europe from the Mediterranean to Persia. Tanacetum larvatum (Gris.) Kanitz, the examination of which is reported, is distributed on elevated rocky ...
The structure, growth and reactivity of electrodeposited Ru/Au(111) surfaces
(Elsevier, 2001)
In order to elucidate electronic effects on the oxidation of CO on small Ru clusters, we investigated this reaction on well defined Ru/Au(111) model systems via parallel in-situ STM studies of the structure and electrochemical ...
The electrocatalytic properties of the oxides of noble metals in the electrooxidation of methanol and formic acid
(Elsevier, 2001)
The electrooxidation of 0.25 M methanol as well as of 0.25 M formic acid was examined on oxides formed on the Au(111) electrode surface in 0.5 M H2SO4 and 0.5 M NaHCO3 at a sweep rate of 0.5 mV/s. In the case of methanol, ...
Electrochemical activation of the electroless deposition of Ni–P alloy and phase structure characterization of the deposit Part II: Single bath system
(Springer, 2001)
The process of electroless Ni plating (EP) was activated by the cathodic deposition of precursors of Ni in the same bath in which EP takes place. The current density (c.d.), duration of cathodic activation, as well as the ...
Application of the Photoacoustic Method for Characterization Of Natural Galena (PbS)
(Springer-Verlag, 2001)
Electron transport properties of single crystal and polycrystalline natural mineral galena (PbS) samples from the Trepča mine, Yugoslavia, were determined using the photoacoustic frequency transmission technique. Their ...
Investigation of Ion-Modificated Silicon by Photoacoustic Frequency Transmission Technique
(The Japan Society for Analytical Chemistry, 2001)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs. the modulation frequency ...
Far Infrared Reflectivity Properties of BaTiO3 Ceramics
(Carl Hanser Verlag, 2001)
Far-infrared and infrared reflectivity measurements have been made on pure BaTiO3, BaTiO3 doped with 5 mol% LiF and (Ba,Ca,Pb)TiO3 at room temperature in the range between 50 and 1000 cm–1. A fitting procedure, based on a ...
Anisotropy in Thermal Properties of Single Crystal α Quartz Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
Anisotropy in the thermal properties in α SiO2 single crystals SC cut mode 1 and mode 2 was investigated using the photoacosutic (PA) frequency transmission technique. The PA amplitude and phase diagrams were measured and ...
Thermoelastic and Electronic Deformation Components of Photoacoustic Signal in Two-layer System
(The Japan Society for Analytical Chemistry, 2001)
A model was derived in order to study the dependence of the photoacoustic signal on the thermal, elastic and carrier
transport properties of two-layer samples. The various systems were considered: the conductor-semiconductor, ...
Some Thermal and Electronic Transport Properties of YBa2Cu3O7-x Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
The possibility of simultaneous determination of some thermal and transport properties of polycrystalline YBa2Cu3O7-x, using a photoacoustic (PA) method was investigated. Both the amplitude and phase PA signals were measured ...
